MgVO oxide with Mg V atomic ratios of 2 2 and 3 2 , were mixed mechanically with α-Sb 2O 4. Chemical changes during oxidative dehydrogenation of propane (ODP) and under calcination treatment were studied. In Mg V( 2 2 ) + α-Sb 2O 4 , magnesium vanadate is contaminated during ODP and a new phase, MgSb 2O 6, was formed after only 1 day of calcination at 823 K. In Mg V( 3 2 ) + α-Sb 2O 4 , no indication of surface contamination or new phase formation was detected during ODP or calcination. The catalytic performances of both mixtures are explained in the light of these results.
